The rumoured couple appeared unabashed to put their affection on full display and was seen getting intimate as they strolled the streets of NYC on July 23, reported E!Online.

"They spent five hours out and about in the Big Apple, where they looked very cozy with one another. The two exchanged sweet kisses and smiles while looking happy and in love," an onlooker said.
